Phil :

You may have blown a fuse on the printed circuit board .. its a 3 to 5 amp fuse, automotive type on the card.

Phil :

Look for that... then find where the wires from the thermostat land in the furnace or inside air handler... a red, white, yellow and green.. small wires.. verify they come from the thermostat.. then jumper red to green and tell me if the fan runs or not.

Phil :

We can go from there, Phil
